How to use this tool

  1. Enter the labeled inputs in the indicated units.
  2. Calculate and compare every output against the stated model assumptions.

Try this example

{
  "s": 5,
  "r1": 1000,
  "r2": 1000,
  "r3": 1000,
  "r4": 1100
}

Accuracy and scope

Unloaded DC bridge with ideal excitation. Simplified analytical model; not a design recommendation or safety certification.
